Fix the red errors identified by Code Analyzer in the left function. If your
function file is not a valid function file due to a red error, how could you
fold it correctly?

BTW, I encourage you NOT to program your GUI using lots of global variables.
Another function you or your GUI's user executes could easily change a
variable A or On or the like in the global workspace without realizing it's
going to break your GUI. Use the handles structure instead.
